Swing Bridge, River Neath

The Swing Bridge at River Neath is a railway bridge with three steel approach spans on the west side and two on the east, supported by cylindrical columns. The central opening span measures about 55 meters and rests on six cylindrical piers that carry the pivoting mechanism.

The structure was built following the Rhondda and Swansea Bay Railway Act and opened in 1892 to improve connections along the river from the docks. Its construction was part of the rapid railway expansion during the coal mining boom in the region.

The bridge shows Victorian engineering design with its rotating mechanism and steel construction, reflecting how industry shaped South Wales. It connected river commerce with the growing railway network that fed the region's coal trade.

The site sits beside the active railway line and is visible from a pedestrian bridge that provides a good vantage point. The area is accessible, but visitors should watch for train traffic and choose a safe spot for viewing or photographs.

The bridge was originally designed as a swing bridge to let larger ships travel upstream, but the mechanism is now permanently locked in place. This function is no longer visible in operation, but the unusual design shows how important river traffic once was to the area.
